Uptake and release of energy substrates, oxygen, and carbon dioxide by the hindlimb of the fasting infant baboon.
Veno-arterial differences for energy substrates across hindlimb tissues were measured in baboon infants at birth and at 6 weeks. Hindlimb glucose uptake was 2.36 +/- 0.80 microM/min in the newly born baboons and 1.81 +/- 0.56 microM/min in the 6-week-old infants. The major precursor release by the infant baboon hindlimb was lactate, although release of alanine and glycerol was significant. These studies complement previous data suggesting that glycolysis is a major pathway for energy production in the infant primate.
